Description

Inner sheet structure with non-adhesive sticker {structure for inner sheet having non-bond sticker}

The present invention relates to an inlay structure provided with a non-adhesive sticker, and more particularly, it is possible to easily attach and detach the non-adhesive sticker to the inlay, and as static electricity can be easily removed, a large amount of inlay can be quickly bound. It relates to an inlay structure provided with a non-adhesive sticker.

In general, a book is a book in which texts, pictures, figures, etc. are printed, or several sheets of paper are bundled together so that texts or pictures can be drawn, and the books are of various types, such as books, students' textbooks and reference books, and children's learning aids. .

The book is composed of a cover, which is a cover of the book, and several sheets of inlay paper with texts or patterns printed on the cover, and the cover and several sheets of inlay are bundled together to bind the book. The inlay includes a paper on which text or a picture is printed, or a paper having a sticker along with the paper.

Since the sticker having a certain pattern is detachably coupled to the paper provided with the sticker, that is, the inlay by a half-cut line, after separating the sticker from the inlay centering on the half-cut line and using it, the used sticker must be stored separately. Not only is there a risk of loss, but there is a very high possibility that the border of the sticker will be damaged or damaged by the half-cut line when removing the sticker from the inner paper. There was also the risk of a safety accident, such as cutting the body if the body comes into contact with it.

In addition, since the inlay provided with the sticker is usually made of a synthetic resin material, static electricity is generated in the process of binding the inlay with the sticker together with the paper inlay, and the inlay is inserted one by one by the generated static electricity. Automatic binding with the bookbinding device is not possible, and for this reason, the binding operation of the book is very inconvenient and difficult as the inlay paper provided with the sticker has to be manually inserted and bound. There was also a problem in that work efficiency was lowered due to demand.

So, in order to solve the above problems, the book was bound by combining an envelope capable of putting a sticker on the surface of some inlay paper among several sheets of inlay or an inlay with a sticker design on it.

However, the cost associated with book binding, such as increasing the time required for bookbinding due to the addition of the process of combining the envelope to the inlay and the process of manually inserting the sticker and the inlay with the sticker design into the envelope coupled to the inlay And there was a problem in that the unit price of the book was increased, as well as the work efficiency according to the bookbinding was lowered. In addition, even after book binding, a phenomenon occurs in the portion where the envelope is located by the sticker contained in the envelope and the inlay provided with the sticker, as well as a layer on the outer surface of the book due to the book being pressed in the process of stacking or transporting the book. There were also problems.

Therefore, in binding the non-adhesive sticker, it is necessary to quickly remove static electricity from the inlay including the non-adhesive sticker to prevent binding defects caused by static electricity and to facilitate the attachment and detachment of the non-adhesive sticker.

1 shows a cross-section of the inlay structure provided with the adhesive sticker of the present invention.

According to the present invention, in a book comprising a cover formed on both sides and several sheets of inlay positioned between the two covers, the cover and each inlay are bound together. It is configured to include an inlay provided with a detachable non-adhesive sticker that is inserted one by one between several sheets of inlay, and the inlay provided with the non-adhesive sticker includes: a sheet paper provided at the bottom; an adhesive applied on the upper surface of the sheet paper and having a certain viscosity so that the sticker can be peeled off and pasted; It is attached to the upper surface of the sheet paper to which the pressure-sensitive adhesive is applied, and includes a film made of a transparent or translucent synthetic resin material including one or more non-adhesive stickers that are detachably coupled, and the rim of the inlay discharges static electricity generated in the inlay. It relates to an inlay structure provided with a non-adhesive sticker, characterized in that it includes a static discharge structure that can be done.

The present invention relates to an inlay structure that can be used in a book, and the inlay structure of the present invention may be used by binding a book only with the inlay structure, or may be bound together with an inlay of another structure or material to constitute one book. In addition, books including the inlay structure of the present invention may be textbooks or reference books of students, and children's learning aids.

The book consists of a cover, which is an outer cover, which is located on both sides of the outside of the book to form the exterior of the book and protects the book, and several inlay sheets located between the two covers, which are inside the book, and the cover and A book is produced by binding several inlays together.

Since the cover is formed to have the same thickness as the inlay or is formed to be thicker and harder than the thickness of the inlay, the inlay of the book is protected by an external physical force by the cover. However, if the purpose is to reduce the cost or light weight of the book, the cover may be made of a paper of a thinner material than the inlay.

The inlay of the book includes various types of inlays, such as an inlay with texts or patterns (pictures, figures, etc.) designed, an inlay that allows you to draw text or pictures using a writing tool, and an inlay equipped with a detachable sticker. can do.

In the case of the present invention, it relates to a book provided with at least one inlay that can be peeled off and pasted with a non-adhesive sticker between a plurality of inlays bound to the book.

The sheet paper 100 is provided on the lower part of the inlay with the non-adhesive sticker, and the non-adhesive sticker 400 can be detachably detached from the sheet paper on the upper surface of the sheet paper 100, that is, it can be peeled and pasted. The pressure-sensitive adhesive 200 having a certain viscosity may be applied so as to be there.

The sheet paper 100 is a part that can be stored by adhering the non-adhesive sticker 400 while maintaining the shape of the inlay. Preferably, it may be made of a material such as paper or synthetic resin material, preferably It can be made of synthetic resin. In the case of sheet paper made of a paper material used in the past, when the non-adhesive sticker is adhered and detached multiple times, the paper layer is separated and adhered to the non-adhesive sticker like the adhesive, which may occur. In particular, in the case of the sheet paper, for storage of the non-adhesive sticker, it is often produced with a thicker thickness than general paper, and most papers have a multi-layered structure to secure this thickness. Therefore, when attaching and detaching the non-adhesive sticker multiple times as described above, the layer of this multi-layer structure may be separated and fall off. In addition, even when manufactured as a single layer, adhesion between the fibers constituting the paper is weakened, so that the adhesive may be peeled off like the non-adhesive sticker. Therefore, in the case of the present invention, the sheet paper may be made of a synthetic resin film or plate, and when made of paper, the synthetic resin may be impregnated or the synthetic resin may be coated on the surface.

An adhesive 200 may be applied to the surface of the sheet paper 100 . The adhesive 200 is used to fix the non-adhesive sticker 400 (see FIG. 1 ), and an adhesive having a certain viscosity may be used so that the sticker 400 can be attached and detached. The pressure-sensitive adhesive used at this time may be an existing pressure-sensitive adhesive, but preferably an adhesive using natural rubber may be used.

The pressure-sensitive adhesive is prepared by mixing 0.2 to 0.5 parts by weight of a peptizing agent and 650 to 700 parts by weight of toluene with respect to 100 parts by weight of natural rubber and stirring at 70 to 90° C. for 8 to 12 hours to prepare a peptized rubber solution; and adding 20 to 40 parts by weight of styrene-isoprene-styrene rubber and 80 to 120 parts by weight of a tackifier to the peptized rubber solution to prepare a mixed solution.

The natural rubber is a natural rubber extracted from a rubber tree. In the present invention, the natural rubber is peptized to prepare a rubber solution, and then, a synthetic rubber, styrene-isoprene-styrene rubber, is mixed to prepare an adhesive. In the case of the natural rubber, since it contains various polymer components, the adhesive strength is excellent, and even when the adhesive is separated, it tends to leave a small amount of residue. However, it has weak durability and is easily decomposed by chemical components. Conversely, the styrene-isoprene-styrene rubber has high chemical stability and durability, but when it is made of an adhesive, it tends to leave residues upon separation. Therefore, in the case of the present invention, it is possible to provide an adhesive that can be neatly separated when separating the adhesive while having high durability and chemical stability by using a combination thereof in an optimal ratio.

The peptized rubber solution may be prepared by mixing 0.2 to 0.5 parts by weight of a peptizing agent and 650 to 700 parts by weight of toluene with respect to 100 parts by weight of natural rubber and stirring at 70 to 90° C. for 8 to 12 hours.

The peptizing agent is a component that can make rubber into a rubber solution by removing the cross-linking of the rubber polymer formed by cross-linking, and serves to reverse the step of preparing a solid rubber by injecting a cross-linking agent into the rubber solution during the manufacture of rubber. carry out The peptizing agent used at this time may be a general peptizing agent for natural rubber. In addition, the peptizing agent may reduce the viscosity of the pressure-sensitive adhesive so as to be easily sprayed and attached to the surface of the sheet paper.

0.2 to 0.5 parts by weight of the peptizing agent may be added based on 100 parts by weight of the natural rubber. When the amount of the peptizing agent is less than 0.2 parts by weight, the peptization of the natural rubber is not complete, so it may be difficult to mix with styrene-isoprene-styrene rubber, which will be described later, and when it exceeds 0.5 parts by weight, an adhesive prepared including the rubber The viscosity may be lowered, and the adhesive force may be reduced.

The toluene is used as a solvent for making the peptized rubber into a solution, and 650 to 700 parts by weight can be mixed with respect to 100 parts by weight of the cheoneon rubber. When the toluene is used in an amount of less than 650 parts by weight, the dissolution of the peptized rubber is not complete, and thus a defect may occur in the adhesive, and when it exceeds 700 parts by weight, the viscosity of the adhesive may be lowered.

The natural rubber mixed with the peptizing agent and toluene as described above can be prepared as a natural rubber solution by stirring at 70 to 90° C. for 8 to 12 hours. At this time, if the stirring temperature is less than 70 ℃ or if the stirring is less than 8 hours, the solution may not be completely generated and thus a defect may occur in the adhesive. can fall In addition, when stirring for more than 12 hours, there is no further effect, so it is uneconomical.

A mixed solution may be prepared by adding 20 to 40 parts by weight of styrene-isoprene-styrene rubber and 80 to 120 parts by weight of a tackifier to the natural rubber solution prepared as described above.

Styrene-butadiene-styrene (SBS) rubber is a synthetic rubber that has a low glass transition temperature (Tg), is composed only of hydrocarbons, has very low surface energy, and has excellent wetting properties. The styrene-butadiene-styrene rubber preferably contains 20 to 30% by weight of styrene, which causes insufficient cohesion when the styrene content is less than 20% by weight, and insufficient adhesion when it exceeds 30% by weight. because there is

Although the said tackifier is not specifically limited, For example, a substituted saturated hydrocarbon resin (synthetic petroleum resin), a rosin ester derivative, a terpene type resin, a phenol type resin, etc. are preferable. In addition, the substituted saturated hydrocarbon resin is not specifically limited.

The tackifier preferably has a softening point of 90 to 160° C., which generally refers to a temperature at which a material is deformed by heating and begins to soften. Thus, the tackifier can begin to deform and soften at 90°C.

When the softening point of the tackifier is maintained at 90° C. or higher, it is advantageous in that thermal strain is reduced by maintaining the adhesion promoter in a glassy state under high-temperature reliability conditions, and high-temperature reliability is easily secured. On the other hand, when the softening point of the tackifier is less than 90° C., the tackifier starts to soften under a high temperature condition, which may cause a decrease in durability. In addition, when the softening point of the tackifier exceeds 160° C., the role of the tackifier at room temperature for promoting adhesion may be insignificant.

The mixed solution prepared as described above may also contain a curing agent. The curing agent may serve to increase the hardness of the pressure-sensitive adhesive to prevent the pressure-sensitive adhesive from flowing, and to increase heat resistance. Preferably, the curing agent is included in an amount of 0.1 to 20 parts by weight based on 100 parts by weight of the natural rubber. This means that when the curing agent is included in an amount of less than 0.1 parts by weight, the curing reaction is not sufficient, so that the heat resistance decreases and the viscosity of the pressure-sensitive adhesive decreases. If it is lowered, residues may be generated, and when it is included in excess of 20 parts by weight, the hardness of the pressure-sensitive adhesive may be increased, which may cause a decrease in adhesive strength.

Such a curing agent may be an isocyanate, epoxy, aziridine, aluminum chelate, etc. suitable for a hydroxyl group, a carbonyl group, a maleic acid group, etc. which are functional groups of the rubber resin as a raw material.

After the pressure-sensitive adhesive 200 is applied, on the upper surface of the pressure-sensitive adhesive, the film is a transparent or translucent synthetic resin material including one or more non-adhesive stickers 400 that are attached to the upper surface of the sheet paper onto which the pressure-sensitive adhesive is applied, and are detachably coupled. 300 may be attached.

One or a plurality of non-adhesive stickers 400 are partitioned on the film 300, and a pattern designed on the non-adhesive sticker 400 is formed to have one complete pattern, or a plurality of patterns are separated. Thus, by connecting and combining them, it can be formed to have one complete pattern.

That is, a part of the film 300 may be separated to constitute the non-adhesive sticker 300 (see FIGS. 1 and 2). Accordingly, when the non-adhesive sticker is detached, the same shape as the non-adhesive sticker The adhesive underneath may be exposed.

The film 300 used at this time may be used without limitation as long as it is a transparent or semi-transparent synthetic resin, but may be made of polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride, polycarbonate or polyurethane, preferably Polyethylene terephthalate having high transparency and excellent ductility and malleability can be used.

The film and the sheet paper may include a static discharge structure for discharging static electricity. In general, when a synthetic resin inlay is used, a large amount of static electricity may be formed by friction, and each inlay may be combined by this static electricity and aligned in an unwanted position. That is, when the synthetic resin inlay is used, since manpower must be used to accurately align each inlay, the automated bookbinding process cannot be performed, and thus the unit price of the produced book may increase. In order to prevent such static electricity, a paper inlay is added between each inlay to prevent static electricity, but the paper inlay makes the book thicker and inserting the paper inlay may increase the unit price of other books, so it is only used in a limited way. there is. In the case of the present invention, static electricity can be rapidly discharged by introducing an antistatic structure to the sheet paper and the film constituting the inlay, and thus, circular binding is possible even when a plurality of synthetic resin inlays are used.

To this end, the static electricity discharge structure may include: a static discharge unit formed with a width of 1 to 5 mm along the edge of the synthetic resin film; and a sheet paper electrically connected to the static discharge unit and including 0.5 to 2 parts by weight of conductive nanoparticles based on 100 parts by weight of the total sheet paper.

A static discharge unit 310 may be formed on the edge of the synthetic resin film. In general, in the case of synthetic resins, due to low electrical conductivity, generated static electricity may be accumulated without being discharged to the outside. Accordingly, in the present invention, the static electricity can be easily discharged to the outside by providing the static electricity discharge unit 310 with a width of 1 to 5 mm along the edge of the film 300 .

The static electricity discharge unit 310 is manufactured to have conductivity, and not only discharges the static electricity accumulated inside the film into the air, but also discharges static electricity to the outside by contacting the metal part of the transfer facility when transferring for bookbinding. can play a role. In this case, since most of the transfer equipment is grounded, static electricity can be easily discharged to the outside, and as a result, it is possible to rapidly discharge the static electricity of the inlay to the outside.

To this end, the static electricity discharge unit 310 may contain 10 to 20 parts by weight of conductive nanoparticles based on 100 parts by weight of the synthetic resin.

The conductive nanoparticles refer to nanoparticles having conductivity, and may be mixed at a certain ratio or more so that the static electricity discharge unit 310 has conductivity, and some of the nanoparticles are exposed to the outside of the film 300 . It may play a role of discharging static electricity to the outside. In this case, the conductive nanoparticles may include nanowires or nanoparticles made of gold, silver, copper, iron, nickel, aluminum, titanium, carbon, or ITO. In addition, the conductive nanoparticles may be nanoparticles coated with the metal. In particular, in the case of nanowires made of the metal or carbon nanotubes made of carbon, 10 to 20 parts by weight of the static electricity discharge part can be included to form a kind of network structure, and thus static electricity generated at each point can be quickly removed. to be delivered to the entire edge of the rim to be released to the outside. In this case, when the amount of the conductive nanoparticles is used in less than 10 parts by weight, the conductivity may be lowered and the static electricity removal effect may be deteriorated.

In addition, the sheet paper 100 may contain 0.5 to 2 parts by weight of conductive nanoparticles based on 100 parts by weight of the total sheet paper. Through this, static electricity generated in the film 300 may be transmitted to the edge portion through the sheet paper 100 and may be easily discharged to the outside through the edge portion.

The conductive nanoparticles included in the sheet paper may include nanowires or nanoparticles made of gold, silver, copper, iron, nickel, aluminum, titanium, carbon or ITO in the same way as the nanoparticles used in the edge part. there is. In addition, the conductive nanoparticles may be nanoparticles coated with the metal. However, when the conductive nanoparticles are included in an amount of less than 0.5 parts by weight, the electrostatic transfer effect by the conductive nanoparticles may be reduced, and when the conductive nanoparticles are included in an amount exceeding 2 parts by weight, the color of the sheet paper may change.

In addition, in the case of the film 300, a conductive nanostructure for transferring the static electricity may be formed (see FIG. 3 ).

To this end, the film of the synthetic resin material, a film body made of a synthetic resin; a linear conductive nanostructure formed on the upper surface of the film body, having a height of 10 nm to 100 μm and a thickness of 1 to 100 nm, with an interval of 10 nm to 100 μm; and a protective layer formed on the upper surface of the conductive nanostructure.

A conductive nanostructure may be formed on the film body, and the conductive nanostructure may be formed linearly to serve to rapidly transfer static electricity generated in the film in both directions. In this case, the conductive nanostructure has a height of 10 nm to 100 μm and a thickness of 1 to 100 nm, and the interval therebetween may be 10 nm to 100 μm. The effect may be reduced, and when formed with a size exceeding the above range and an interval smaller than the above range, the transparency of the film may be decreased due to the conductive nanostructure.

The conductive nanostructures are formed by (a) applying a macro-pattern material to the surface of a polyethylene terephthalate film; (b) forming a macro pre-pattern by etching the macro pattern material at regular intervals; (c) applying a conductive nanomaterial on top of the exposed film and the remaining macro pre-pattern after the etching is completed; (d) attaching the conductive nanomaterial to the side surface of the macro pre-pattern through a nickname; and (e) removing the macro pre-pattern.

The step (a) is a step of applying the macro pattern material 330 to the polyethylene terephthalate (PET) film 320 (FIG. 3 (a)), and the macro pattern material 330 is applied to the film 320. It is a step of preparing a layer on which a macro pattern will be formed by applying it to the surface. At this time, the macro pattern material may be applied to the surface of the film through a method such as spraying, roller coating, or vapor deposition, and since the height of the conductive nanostructure is determined in proportion to the thickness of the macro pattern layer, the thickness of 100 μm It is more preferable to apply by using vapor deposition that can be applied uniformly.

The macro pattern material 320 may be made of polystyrene, chitosan, polyvinylalcohol, polymethyl methacrylate (PMMA), a photoresist compound, or a conductive polymer. The macro pattern material is formed in a predetermined shape by a lithography or imprinting process, and a conductive nanomaterial is deposited on the side surface by etching. In this case, the height and spacing of the deposited conductive nanomaterial may be adjusted by adjusting the height and spacing of the macro pre-pattern.

After the macro pattern material 320 is applied, the macro pattern material is etched at regular intervals to form a macro pre-pattern (FIG. 3(b)). In this case, the etching may be performed using a lithography or imprinting process as described above, and the lithography or imprinting process may be performed using the same process as previously known.

After the macro pre-pattern is formed as described above, the conductive nano-material 340 may be applied on the pre-pattern (FIG. 3(c)). The conductive nanomaterial 340 is gold, platinum, silver, copper, aluminum, zinc oxide, chromium, indium tin oxide, nickel, iron, titanium, molybdenum, silicon, zinc oxide or titanium oxide. can be used Since the conductive nanomaterial 340 is uniformly applied to the surface of the film, it is uniformly attached not only to the upper portion of the macro pre-pattern, but also to the surface of the film exposed due to a lithography or imprinting process.

After the conductive nanomaterial 340 is applied as described above. This may be nicknamed and the conductive nanomaterial may be attached to the wall surface of the macro pre-pattern 330 (FIG. 3(d)). Looking at this in detail, the conductive nanomaterial 340 scatters in all directions by the etching. At this time, in the case of the conductive nanomaterial attached to the exposed film, it does not flow out of the macro pre-pattern and is not leaked out of the macro pre-pattern. can be attached. That is, after the etching is completed as described above, the conductive nanomaterial may exist on the wall surface of the macro pre-pattern. To this end, the nickname may be performed as a milling process, particularly an ion milling process, in which a plasma is formed using a gas under a pressure of 0.1 mTorr to 10 mTorr and then the plasma is accelerated to 100 eV to 5,000 eV. In addition, the gas used for the ion milling is preferably selected from the group consisting of argon, helium, nitrogen, oxygen, and a mixture thereof.

As described above, when the conductive nanomaterial is attached to the side of the macro pre-pattern and then the macro pre-pattern is removed, only the conductive nano-material remains, and a conductive nano-structure can be formed on the film using this ( 3(e)).

The conductive nanostructure as described above may be formed on the entire film, which means that the conductive nanostructure is also formed inside the non-adhesive sticker manufactured by cutting a part of the film. However, since the non-adhesive sticker has a certain shape and has to have an appropriate color, the shape can be expressed through printing on the conductive nanostructure.

Therefore, the non-adhesive sticker 400 may further include a printed layer between the conductive nanostructure and the protective layer.

The printed layer may be printed to have a constant shape, and the non-adhesive sticker may have a constant shape. In this case, the printing may be performed using gravure printing or offset printing, which is a type of lithographic printing, and preferably offset printing may be used.

To this end, the printing step may include supplying water to a portion without a shape on the surface of the disk roller for shape printing, and then supplying UV curing ink to a portion having a desired shape; transferring the ultraviolet curable ink to the offset printing roller by bringing the offset printing roller into contact with the surface of the shape printing disk roller; printing the ultraviolet curable ink by pressing the offset printing roller on the upper surface of the film on which the conductive nanostructure is formed; and supplying UV light to the UV curable ink to cure it (see FIG. 4 ).

The printing step of the ink may be performed in the same manner as the generally used offset printing. That is, water is applied to the surface of the disk roller having a predetermined shape, excluding the shape, and UV curable ink can be supplied to the desired shape. After that, the offset printing roller is brought into contact with the surface of the shape printing disk roller to transfer the UV curable ink to the offset printing roller, and the transferred ink is compressed on the surface coating layer and UV is supplied to cure the ink. can be done

In addition, in the case of the offset printing, monochromatic printing may be performed, but since most stickers are manufactured to have multiple colors, a process of sequentially printing the three primary colors may be performed, and black and white to make the white and black surfaces more vivid It is also possible to perform five-color printing including That is, in the case of three-color printing, three colors of yellow, blue, and red are used, and white can be expressed by exposing the background color. In the case of three-color printing, the yellow 510, blue 520, and red 530 are Five-color printing can be performed by adding white 540 and black 550 . In addition, after each color is printed, it is preferable to cure the ink within a short period of time by supplying 560 UV to each of the colors to cure the ink. In the case of the present invention, if one color is printed and the next color is printed in a dry state, each color is mixed and smeared or a different color is generated on the roller, resulting in poor printing. Therefore, it is desirable to prevent smearing or color transfer by performing UV curing after completing the printing of each color.

In addition, when performing multi-color printing as described above, color bleeding may appear depending on the positional alignment between each color. it is preferable

The guide printing is a part printed to align the positions of each roller by printing a certain shape on one side of the film. By doing this, you can prevent unwanted shapes from appearing on the printed side of the sticker. The guide printing may be printed in various shapes so as to determine the relative positions of the roller and the film, but is preferably printed in a crisscross pattern so that the roller can be moved forward and backward and left and right. In addition, the guide printing may be used for quality inspection and manual adjustment of each roller after printing is completed. When the guide printing is performed at the same location for all colors, a black guide printing is finally output. However, when one color roller is abnormally aligned, only the color corresponding to this roller may be printed out of the guide print shape, which can be visually observed to determine the printing defect. In addition, after checking the alignment of each color as described above, the rollers are manually aligned to be utilized as basic data for automatic alignment, which will be described later.

In addition to the manual alignment as described above, each roller can be automatically aligned. Looking at the automatic alignment method of the rollers in detail, when the guide printing is performed on the first roller, the first position detecting means interlocked with the second roller reads the position of the cross. Based on the read position, the first position detecting means calculates the position of the roller according to the transfer upper limb. 2 The position of the roller is finely aligned. In this case, it is preferable that the guide printing unit is located at the starting point of the offset printing, and the position information sensed by the first position detecting means is provided before the second roller finishes the previous printing and the guide printing appears, that is, each It is transmitted to the second roller in the blank part existing between the printed materials to align the second roller. By repeating this for each color, it is possible to finally print all the rollers aligned according to each print color and the position of the film.

In the present invention, since a conductive nanostructure is formed on the surface of the film to be printed, when an ink for conventional offset printing is used, bleeding may occur between the conductive nanostructures due to capillary action. In order to prevent this, the ink preferably has a viscosity of 20 seconds or more and 50 seconds or less when measuring the viscosity using a cup viscometer (No. 3). If the viscosity is less than 20 seconds, the offset ink may bleed due to the low viscosity, and if it exceeds 50 seconds, smooth printing may be difficult due to the too high viscosity.

It is preferable that the film having the nano-structure formed on the surface as described above be surface-treated using plasma. In the case of the film, not only may foreign substances remain on the surface, but also it may not be easy to fix the ink for offset printing, which will be described later, due to the nanostructure existing on the surface. Therefore, by performing a plasma treatment on the surface of the film, it is possible to remove foreign substances and perform a surface activation treatment at the same time.

To this end, the plasma surface treatment is preferably performed using atmospheric pressure plasma formed at a voltage of 50 to 100 kV under an inert gas atmosphere. When the voltage is less than 50 kV, it is difficult to form a smooth plasma, and when it exceeds 100 kV, the nanostructure may be damaged due to the plasma. In addition, since the film has a conductive nanostructure on the surface and is preferably printed by a roll-to-roll process, it is preferably surface-treated using atmospheric pressure plasma.

A protective layer 350 may be formed on the surface of the film. The protective layer is a film selected from the group consisting of polyethylene, polypropylene, polyethylene terephthalate, polyvinyl chloride and polycarbonate containing 1 to 5% by weight of titanium oxide nanoparticles, and polytetrafluoroethylene is coated on the surface there may be

The titanium oxide nanoparticles reflect ultraviolet rays incident on the film to prevent discoloration of the printed layer inside the film and to prevent deterioration of the film. When the titanium oxide nanoparticles are mixed in less than 1% by weight, it is difficult to expect a UV reflection effect by the titanium oxide, and when it exceeds 5% by weight, cloudiness may occur and the film may become opaque.

In addition, the surface of the protective layer 350 may be coated with polytetrafluoroethylene. In general, the surface of the protective layer or non-adhesive sticker is made of a polymer resin. However, when the polymer resin film is left in contact for a long period of time, the two films in contact are fused and adhered. In the case of the existing polymer film inlay, overlapping paper inlays are used to prevent this, but this paper inlay not only makes the book thicker than necessary, but also prevents the adhesion of these films when the paper inlay is removed by external force. The downside is that it cannot be stopped. Therefore, in the present invention, it is preferable to coat the protective layer on the film surface with polytetrafluoroethylene to establish adhesion between the two films.

The polytetrafluoroethylene is a kind of polymer resin called “Teflon” and can be applied in a thin thickness, and once hardened, it hardly interacts with other materials, so it is used as a lubricant or a lubricating layer. In the present invention, by coating the polytetrafluoroethylene on the protective layer, it is possible to prevent the films from adhering to each other even when they are in contact for a long period of time.

A groove may be formed on the rear surface of the film to control adhesion with the pressure-sensitive adhesive (see FIG. 5 ). That is, the lower surface of the film body may include grooves having a depth of 0.1 to 100 μm and formed at intervals of 0.1 to 200 μm.

The groove is preferably formed in the same direction as the conductive nanostructure, that is, in a horizontal direction. In the case of the upper limb conductive nanostructure, since it has complete malleability and ductility, destruction can be minimized even when bending to detach the non-adhesive sticker, but when bent multiple times, the conductive nanostructure is damaged and static electricity is removed effectiveness may decrease. Accordingly, damage to the conductive nanostructure can be minimized by maintaining a constant bending direction by aligning the groove and the precursor wire nanostructure in the same direction. In particular, when the rear surface of the film is processed to have the groove, it can be easily bent in the same direction as the direction of the groove formation, so it is possible to easily adhere the non-adhesive sticker without damaging the conductive nanostructure. In addition, when bending in a direction perpendicular to the groove, the radius of bending due to the groove may be maintained to be large, thereby preventing damage to the conductive nanoparticles.

In addition, the adhesive force of the release paper can be adjusted according to the shape and density of the groove, and when an external force is applied to remove the release paper, the groove can be easily removed while deforming (see FIG. 7 ).

In the present invention, the term groove refers to depressions formed at regular intervals. In the present invention, valleys may be formed on the surface of the film at regular intervals so that the valleys and the protrusions are alternately positioned.

Looking at the grooves in detail, the grooves are formed by alternately repeating valleys and protrusions. In this case, the portion in contact with the pressure-sensitive adhesive corresponds to the protrusion, and by adjusting the shape of the protrusion, the contact area with the pressure-sensitive adhesive may be adjusted and the adhesive strength may be adjusted.

As an example, when the protrusion has the shape of a semicircle with a small diameter, the depth of the valley is also lowered, so that when pressing to attach the release paper, it can be attached with the adhesive in a wide range, and as a result, the adhesive force can be strong. There is (Fig. 6 (a)).

Conversely, in the case of having a semicircle with a large diameter, even if pressure is applied as the bone portion deepens, a portion of the bone may remain unattached, and thus it is possible to have a low adhesive force (Fig. 6(b)). )).

In addition, in order to further control the adhesive force, the protrusion may be manufactured in a shape constituting a part of an ellipse, and may be manufactured in a trapezoidal, rectangular, or triangular shape (FIG. 6(c) and (d)). That is, by controlling the shape and spacing of the protrusions, it is possible to adjust the adhesive strength even if the same adhesive and release paper are used.

In addition, the groove may facilitate separation from the adhesive when the non-adhesive sticker is removed. When the non-adhesive sticker is detached, an external force is applied to the non-adhesive sticker. In particular, there are many cases in which the side surface of the non-adhesive sticker is removed by stretching. In this case, the groove may be deformed, and accordingly, deformation may appear on the adhesive surface and thus may be easily removed. In particular, when stretching in the same direction as the direction of the grooves, the gap between the grooves is narrowed, and the area of the protrusion is reduced. As a result, the adhesive surface is reduced, so that the non-adhesive sticker can be detached naturally.

In addition, the grooves may have a depth of 0.1 to 100 μm, and may be formed at intervals of 0.1 to 200 μm. When the groove has a depth of less than 0.1 μm, the adhesive force control by the groove may not appear, and if it has a depth exceeding 100 μm, the thickness of the film may decrease and durability may be reduced, and the interval of less than 0.1 μm may be reduced. In the case of having, the durability of the non-adhesive sticker may be deteriorated, and when formed at an interval exceeding 200 μm, the adhesive surface may be widened, so that control of the adhesive force may not appear.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications are possible by those having the knowledge of, of course, and these modifications should not be individually understood from the technical spirit or prospect of the present invention.
